Answer: Option A
Answer: (a)
Petroleum is a fossil fuel derived from ancient fossilized organic materials, such as zooplankton and algae. Vast quantities of these remains settled to sea or lake bottoms, mixing with sediments and being buried under anoxic conditions.
As further layers settled to the sea or lake bed, intense heat and pressure build up in the lower regions.
